Current Innovations in Genetics and Plant Breeding (Volume - 4), edited by Dr. S.P. Giri and Dr. Anil Kumar, provides in-depth insights into modern breeding techniques addressing key agricultural challenges. This volume discusses essential topics like drought tolerance in wheat, the role of mutation breeding, optimization of maize leaf angles, and breeding for sterility mosaic disease resistance in pigeonpea. It also explores biological nitrogen fixation in legumes and the nutritional potential of pseudocereals in minor millets. The book highlights physiological, biochemical, and molecular tools integrated with classical breeding to improve yield and stress resilience in crops. Detailed chapters by renowned researchers cover both theory and practical advancements, making it a vital resource for scientists, breeders, and students. With a strong focus on sustainable agriculture, the book contributes to building climate-resilient and nutritionally secure crop systems through innovative genetic interventions.
